ABSTRACT:
A system that is usable with a well includes a closed loop network that is located entirely downhole in the well. The system also includes valves that are located in a wellbore of the well and are interconnected by the closed loop network. Each valve is associated with a different isolated region of the wellbore and is adapted to regulate a flow through the valve based at least in part on a flow condition of the isolated region associated with the valve and a flow condition of each of the other isolated regions.
